Refined Power: Stealth Black Porsche 911 Turbo S Cabriolet Gets Detailed, Protection & Upgrades

The Porsche 911 Turbo S Cabriolet represents the pinnacle of open-air performance in the modern 911 lineup, and this particular black-on-black example takes that reputation to a new level with a carefully curated set of enhancements added at our Hawthorne, California, facility. From the factory, the 992 Turbo S Cabriolet is already an engineering marvel—its 3.8-liter twin-turbocharged flat-six produces a staggering 640 horsepower and 590 lb-ft of torque. Thanks to Porsche’s lightning-fast PDK (Porsche Doppelkupplung Getriebe) dual-clutch transmission and all-wheel drive, it launches from 0 to 60 mph (0-100km/h) in just 2.7 seconds. Furthermore, the 911 Turbo S is capable of reaching 124 mph (200km/h) in under 9 seconds, and entertaining a top speed of 205 mph, all while delivering razor-sharp handling and everyday usability.

But this example is far from stock. The Bulletproof Auto Spa team has transformed this Turbo S Cabriolet into a true stealth performance machine, combining aesthetics, protection, and mechanical upgrades that sharpen its form and function. At first glance, the vehicle stands apart thanks to a full-body XPEL Stealth Paint Protection Film (PPF), which transforms the factory gloss black finish into a satin sheen while shielding the paint from chips, scratches, and UV exposure. In addition, in places where the vehicle features aftermarket gloss carbon fiber, such as the underbody kit, the XPEL Ultimate Plus PPF (Paint Protection Film) was used to preserve its high-gloss appearance without sacrificing protection.

To ensure long-term brilliance, the entire vehicle is coated in a professional-grade ceramic coating, delivering superior hydrophobic properties, resistance to environmental contaminants, and a strikingly smooth finish. The XPEL Prime XR Plus nano-ceramic window tint complements the package by providing maximum infrared heat rejection with minimal visual distortion—keeping the cabin cooler and more private, even under intense sunlight.

Protection extends beyond the paintwork. Bulletproof Auto Spa wrapped the gloss black interior trim with XPEL Ultimate Plus, shielding vulnerable surfaces from scratches and wear while retaining a showroom-new appearance. The full wheel barrels and calipers have been treated with high-temp ceramic coating as well, dramatically reducing brake dust buildup and simplifying maintenance. And by that we mean that a plain old pressure wash with just water will do the trick in most situations. Something busy owners will definitely appreciate.

A subtle yet functional touch is the installation of Rennline radiator protection grill screens, which shield vulnerable front cooling components from road or track debris—a must-have for spirited drivers.

A combination of premium carbon fiber aero components further enhances the visual and aerodynamic character of the car. The front end features a bold 1016 Industries carbon fiber front lip and matching carbon fiber mirror caps. Along the sides and rear, TechArt carbon fiber side skirts and a rear diffuser add aggressive styling cues while reducing lift at high speeds.

Handling is dramatically improved thanks to a Bilstein EVO SE Coilover Suspension Kit, specifically designed for the 992 chassis and featuring electronically adjustable damping. The kit lowers the car’s center of gravity and increases responsiveness without sacrificing ride comfort—a perfect match for both aggressive street driving and canyon carving.

Under the surface, Bulletproof Auto Spa worked to unleash even more performance from the already potent Turbo S powertrain. A CSF Intercooler System provides improved cooling efficiency under boost, while an upgraded intercooler pipe kit improves airflow and throttle response across the powerband.

Exhaust gases are handled by a motorsport-grade Akrapovic Slip-On Race Line Titanium Exhaust System, mated to Akrapovic black titanium tailpipes. Not only does it reduce backpressure and shed weight, but it also transforms the exhaust note into a more visceral, commanding tone—one that matches the car’s newfound performance.

All of this is optimized through the use of a COBB Accessport, providing custom tuning capability and real-time performance data monitoring. With upgraded hardware and a tailored tune, this 911 Turbo S Cabriolet now exceeds factory limits in performance while maintaining reliability and drivability.
